prostate gland lobes in human and mouse

[cmungall]

PMID:15163300 claims the human prostate lacks lobes. The same claim is also made in PMID:3308446 via:

[Term]
id: MP:0001163
name: abnormal prostate gland anterior lobe morphology
namespace: MPheno.ontology
alt_id: MP:0000663
def: "any structural anomaly of the rodent prostate lobe that appears as a thin tubular structure, attached to the lesser curvature of the paired seminal vesicles" [PMID:12645922, PMID:3308446]
comment: In rodents, the prostate gland consists of three lobes, the anterior prostate (AP; also known as the coagulating gland), the dorsolateral prostate (DLP), and the ventral prostate (VP). These lobes are arranged circumferentially around the urethra and display characteristic patterns of ductal branching and protein secretion (PMID:3308446). In contrast, ***the adult human prostate lacks discernible lobular organization*** and, instead, completely envelops the urethra at the base of the bladder (PMID:3308446).

xref: MA:0002422 ! prostate gland anterior lobe

(confusingly the term 'lobular' not 'lobar' is used here)

@gkoutos previously checked this (email exchange, 2011) and found it dubious. He checked with Onard and a few anatomists (FMA includes lobes of the prostate). So I think we agree it has lobes.

@cindyJax - should the MP comment be changed?

While we're here, there seems to be some confusion over the AP and the CG in MA/EMAPA

• MA:0000402 ! coagulating gland [xref: EMAPS:3524528]
  • EMAPA:35245 ! coagulating gland
• MA:0002422 ! prostate gland anterior lobe [xref: EMAPS:2979428]
  • EMAPA:29794 ! anterior prostate gland

According to MP, these should be merged, what do you think @tfhayamizu?

Recent discussion about this, although I can't recall the details right now. I will revisit this, consulting our GUDMAP colleagues (who have been extensively working on the lower urinary tract and reproductive systems) as well as pathology references. "Comparative Anatomy and Histology: A Mouse and Human Atlas" by Piper M. Treuting and Suzanne M. Dintzis, recommended highly by pathologists I have consulted, has often been a useful resource for mouse vs. human issues..

Human prostate has four lobes.

There appears to be some disagreement here.

According to the above-mentioned reference -- CHAPTER 18 – MALE REPRODUCTIVE SYSTEM (written by Sue Knoblaugh, Fred Hutchinson Cancer Research Center, and Lawrence True, University of Washington School of Medicine):

"The mouse prostate is divided into four distinct lobes: anterior prostate (coagulating gland), dorsal prostate, lateral prostate and ventral prostate" ("Dorsal and lateral lobes are sometimes grouped together as the dorsolateral lobe") and "each lobe is histologically distinct."
"Conversely, the human prostate is a single organ. " "The gross human prostate is a single alobular structure," "divided into three concentric zones" and "organized as histologically similar zones by the pattern of branching of the prostate ducts "

[RDruzinsky]

Just heard a talk on the aging genito-urinary system in males at the American Association of Anatomy annual meeting. Speaker described the 4 lobes. I can find refs.

To what extent is the disagreement here about the prostate, vs about the definition of 'lobe'

I concur that there are groups that used the "lobe" terminology; also pointing out that some do not. The WP article summarizes this as: "The "zone" classification is more often used in pathology. [Hence that view is presented in in the pathology reference.] The idea of "zones" was first proposed by McNeal in 1968. McNeal found that the relatively homogeneous cut surface of an adult prostate in no way resembled "lobes" and thus led to the description of "zones." Also, "The "lobe" classification is more often used in anatomy." Finally, it states that the anterior, posterior and lateral lobes "roughly" correspond to parts of the transitional, peripheral and central zones, respectively. The important thing to recognize here is that there doesn't appear to be evidence supporting any developmental or functional correlation between similarly named "lobes" for the mouse and human, at least not that I have been able to find.

Hi, I agree. After doing some reading, I don't really think that the "zones" of the prostate, as described by McNeal, are not really lobes at all, although many clinicians and anatomists describe them as such.
